The hot arid regions of India in economically and environmentally disadvantaged part of the country with unique problems. These, ecosystems are highly fragile and large liabilities causing severe impediments in development programmes.

Mango is a widely spaced fruit tree comprising a good number of commercial varieties. Mango fruit crop provides opportunities of utilizing the land spaces to its maximum, particularly during the initial years of establishment. Thus, an attempt was made to study the effect of mango varieties on the yield of wheat sown in its inter spaces. Dec 2006
